IMPROVEMENT IN SWITCH AND S IGNAL LOCKING DEVICES.

Speciiication forming part of Letters Patent No. 179,290, dated J one27, 1875; application filed May 1, 1876.

' To all. whom it may concern:

Be it known that we, SMITH H. FINGH, of the city, county, and State ofNew York, and HENRY MOORE, of Orange, in the county of Essex and in theState of New Jersey, have invented a new and Improved Switch and SignalLever Locking Device, of which the following is a specification:

Figure 1 is a front view of a pair of levers to which our improvementhas been applied, the stand being. shown in section. Fig. 2 is a sideview of the same, the stand being shown in section through the line was,Fig. 1. Fig. 3 is a detail view of one of 'the sliding bars.

The object of this invention is to furnish an improved attachment forswitch and signal levers, which shall be so constructed that themovement of the detent to release a lever will lock the other levers, orany previously arranged number of them, before the said lever has begunto move, and so that the said levers cannot be moved until the first onehas been brought back to its place an t secured by its sides of thelevers O, and engage with notches in the guides B to keep the saidlevers in place when adjusted.

The dctents D are extended along the rear side of the levers C, and havelugs 01 formed upon the sides of their lower parts, in which are formedinclined slots, to receive pins 6 attached t0 the bars E. The bars Eslide in guides in the stands A, and to them are attached hooks 6 onefor each lever, to be locked by the movement of the detent of one ofsaid levers, and which hook into holes d in the detents of said levers.

By this construction, as one of the detents D is raised to release itslever O, the inclined slot of the l'ngd acts upon the pin c of thesliding bar E, and forces the hooks e of said bar into holes d in thedetents D of-the other levers C, so that the said levers will be lockedbefore the lever being operated begins to move, and will be held lockeduntil said lever has been brought baclt'to its place, and the detent hasdropped into place.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

The combination of the pins 0 and the hooks e of the sliding bars E,with the slotted lugs d and the holes (1 of the detents D, substantiallyas herein shown and described.
